Sewer Odor and Corrosion Control Services

The City of Dallas is seeking qualified vendors to enter into a thirty-six-month Indefinite Delivery/Indefinite Quantity (ID/IQ) service price agreement for sewer odor and corrosion control services, primarily involving the purchase and injection of Liquid Ferrous Iron Salt (FeSO4), Liquid Ferrous Chloride (FeCl2), and Bioxide into the wastewater collection and treatment system. The goal is to mitigate hazardous off-gases, enhance wastewater quality for improved treatment and disposal, and protect infrastructure from corrosion. Services will be ordered on an as-needed basis under delivery orders issued during the contract term, with no guaranteed minimum quantities. The solicitation, identified as BR26-00030262, was posted on May 21, 2026, with proposals due by June 26, 2026, and submissions must be made electronically through the City’s Bonfire portal. The NAICS code for this procurement is 221320, and performance is required across various locations throughout Dallas, with all deliveries FOB at the City’s designated sites or DWU facilities. Award will be based on a trade-off evaluation process, where the most advantageous proposal—not necessarily the lowest price—will be selected after assessing responsiveness, responsibility, and a range of non-price factors. Local preference grants five points to Dallas-based businesses, while Small Business Enterprise (SBE) utilization can earn up to six points based on achieving or exceeding participation goals. Additional points are available for documented mentor-protégé engagement, past subcontractor performance, and community outreach efforts. Mandatory compliance criteria include Living Wage adherence, submission of W-9 and Safety Data Sheets, and strict adherence to federal, state, and local regulations including OSHA, EPA, and TCEQ. All chemical shipments require accompanying documentation such as certified net weight tickets, certificates of analysis, lab reports, and SDS, with vehicles equipped with pneumatic unloading systems. Remote 24/7 tank monitoring is mandated for product integrity. Contractors must also comply with Texas state laws prohibiting boycotts of Israel and affiliation with designated terrorist organizations, follow EEO and non-discrimination mandates under Executive Order 11246, and provide indemnification against claims arising from negligence or breach. Insurance requirements are stringent—self-insurance is permitted only for entities with at least $100 million net worth and city-approved reserves. No contract assignment is allowed without written approval, and the original contractor remains fully liable. Invoices must
